Before understanding the basic principle of random access memory, which is mainly through the charge and discharge of the capacitor to ensure the data read and write, when the power loss, the data is lost, this section we mainly learn the basic composition and principle of Flash. Now flash in the embedded system and the status of the hard disk on the PC similar to the system used to save the system, data and application sequence, and memory loss after the power, it can be permanently saved after

The submission form inserts the data with insert into, but always blank, without prompting for an error. Excuse me, is there a problem? @header ("content-type:text/html; Charset=utf-8 "); require_once ' inc/site_config.php '; require_once ' inc/db_connections.php '; require_once ' inc/ Function.php '; mysql_query (' Set character set "UTF8" '); Session_Start (); if ($_request[' action ']== ' Postreg ') {$sql _check_usr= "select * from ' Reguser ' where ' UserId ' = '". $_ session[' uid ']

If you want to keep some of the data to a U disk, then you have to consider the life of U disk, U disk storage environment, temperature, humidity, etc. will be a U disk to a certain life effect, there is a general U disk is the use of the term is wiped 30000-10000 times. The general use of MLC particles of u disk can be erased more than 10,000 times, and the use of SLC particles of U Disk Service life is up to 100,000 times. If your data is stored for

flash memory, so the price of SSDs is also higher. Take the same 1TB capacity as an example, the traditional mechanical hard disk is only about 800 yuan, and SSD needs at least 2000 yuan. So, what is the read-write life of SSD solid-state drives? There are also two parts to be divided. SSD flash particles are usually two particles of SLC and MLC, whereas SLC can read and write about 100,000 times and MLC

characteristics: 1, the speed is slow, the market share is very high. 2, the quality of flash chip is very poor, basic is the use of black film. 3, JS are like sales, because the price is low. Flash manufacturers do not need to compare, Samsung, Intel, Heidelberg, Toshiba are manufacturers. But there are SLC, MLC, TLC points. SLC (Single-level Cell) is 1bit/cell, the speed of long life, the price is e

In previous projects, we understood the wear and loss balance of flash memory, and manufacturers were looking for the cause of the loss around the way they worked. The technology used by the supplier to solve the wear problem aims to make the solid-state hard disk based on flash more predictable, although the implementation is still long, but predictability is the key to the firm's reliance on solid state storage. There is another key factor that affects the storage life of solid-state hard disk

the parameters of SSD, will be labeled with SSD read and write speed, some marked is the average, some marked is the maximum read and write speed, we can through the average and the maximum value to do a comprehensive reference, the larger the number, SSD solid state hard disk performance is better. Three, solid state hard disk particles In the solid state drive parameters, there are also particles, solid-state hard disk particles have three types, respectively,

rate. It also uses the built-in error correction function to make up for noise and other interference. VDSL is suitable for short-distance transmission. Currently, we recommend that you use four types of VDSL encoding: CAP and DMT.), DWMT, and SLC. DWMT (Discrete Wavelet Multitone) is a multi-carrier modulation system that uses a single-carrier Wavelet transform. SLC (Simple Line Code) is a baseband signal

8.NandFlash principle AnalysisThis section is mainly about Nandflash knowledge, first of all, the role, classification and access of Nandflash. Role analysis: In the personal PC, use the hard disk to store the operating system, data and other information. In the field of embedded, it is called Nandflash with HDD function. So Nandflash is the storage of information. Nandflash classification: Outline of SLC principle:Outline of MLC Pri

utilization. So it seems, is not the smaller the better? Because a cluster is the smallest managed storage unit of a disk, if a file reads 4 units and 400 units, which one do you think is faster? And the current large-capacity hard drive has not cared about those k, cluster this thing is not necessary too small. Voice-over 1: The smaller the file, the more waste of storage space AH? So it is. VoiceOver 2: Big also not suitable, small also not suitable, I do not understand. With Microsoft de

1. The master chip is the core of SSD and determines the performance and stability. Mainly include Intel, JMF, Samsung, Indilloud, among which intel and Samsung are the leader, indilloud is the new expensive, and JMF is mainly oriented to low-end markets. 2. the cache chip assists the master chip in data processing to improve and stabilize performance. Some low-end products will save the cache dram chip for cost reasons. 3. NAND Flash chips mainly include Intel and Samsun. Most SSDS Use Samsung
